` To all whom t muy] concern Be `1t knownthat 1,EDWARD J. MILES, a citizen of the United Lchartes,` and a resident of Newton, in the county ofJasper and State 5 of lowa, have invented a certain new and useful Assembling land Disassembling Tool, of which the following is a specification.

The object of'my invention is to provide a tool of simple, durable and inexpensive con- '10 struction for the convenient assembling and disassembling' of generators, starting motors and other mechanism.

More particularly, it is my obj ect to provide a tool, having parts conveniently arranged and constructed for readily taking,`

apart mechanisms of the kindunder considy eration and putting them together with a maximum saving; of time and work.

With these and other objects in view, my

invention consists in the construction, ar-

rangement and combination of the various parts ofmy device, whereby the objects contemplated are attained as hereinafter more fully set forth, pointed out in my claims, and'illustrated in the accompanying drawing-s, in which; p

Figure 1Q shows a view, partly in section of a tubular accessory member.

.Figure 13 shows a perspective view of a there are few tools",` which are especially adapted tor the purpose and" frequently in taking the generator apart bycrudemethods" and with such tools as are at hand, the gears, bearings anddelicate parts are injured. Itis my purpose tov provide a tool with which the entire process of taking the generator apart and putting it back together again" may be readily and easily carried on in a minimum time with a minimum likelihoody l of injuringl the delicate parts.,

l will describe myimproved tool "in con-` nection with the explanation oi taking apart a well-known generato-r.

My tool comprises a supporting` base indicated by the reference character 10, which may be bolted to a bench or the like, ifdesired.

A t what l may call the front end of the base 10 is an upright member 11 forming the screw support, and in which the threaded rod or screw 12 is mounted. Att the ends oi' the upright 11 are members 13 extending,l rearwardlyl from the support 11 adjacent to the outer side edges of the basev 10, as shown for instance in Figures 1 and 2.

rlhe members 13 form the front plate standards, and at their rear portions fareprovided with vertical-grooves or slot`s`14`ar`- ranged to register with each other, as shown for instance in Figures 1 and 2, which slots are designed to receive plates. Mounted at the rear portion of the base 10 for longitudinal -sliding movement with relation to said base is a cross member 15, having the rear plate standards 16, which are provided with the registering vertical grooves or slots 1.7 to receive plates hereinafter referred to.

The cross member 15 has on its lower side a. downwardly projecting rib 1S, having bevelled edges 19 arranged to coact with the bevelled edges 2O of a .longitudinally arranged slot 21 in the rear portion of the base 10.

Mounted in the base 10 is a set screw 22 i for locking the rib `18 to the cross member 15 and the rear plate standards 16 in any of the adjusted positions of said parts.

The screw 12 at its outer ends has flat sides k23 received between the arms 24 o1c a crank handle 25, which is pivoted to said screw by means of a pint-le 26 extending through the arms 24 and the end of t-he screw 12.

At its inner end. the screw 12 has a reduced smooth-surfaced, cylindrical portion 27 art he inner end ot' which is a conical point 28.

rllhe various detachable parts of my improved. tool I .will describe in connection n with the explanation o1 the use of the tool.

.Figure 1 by the refe-rence character 29. At

one end `of the casing 29 is a mLovable plate 30. v

Received within the casing 29 is the rotor having the shaft 32 on one end of which is the .pinion 33.

The base 10 is provided on its upper surtace between the front and rear plate standards With laterally spaced longitudinally arranged ribs 34,

The iirst step in disassembling the genen atorinvolves the removal of the. pinion 33. The pinion 33 has a hub 35. A pin 36 extends through the hub 35 and the shaft 32. ln some generators, nut is pla-ced on the shaft.

ln removing the pinion 33, the generator is placed lengthwise on' the to'ol. resting on the. ribs 34. l use a plate, shown. in Figures 5 .and 6, and indicated by the reference numeral 37, which is slidably received in the grooves 14. The plate 37 has in its upper` edge al suitable recess 38 designed to receive the .shaft of the generator. ln one side, the plate 37 has a vertical groove 40, shown in Figures 5 and 6,

' llheshaft 32 rests in the recess 3S and the pin 36 is arranged. inline with the groove 49. The plate then forms a support for the shaft and the hub of t-he pinion 33, and the pin 36 can be easily driven out.

The plate 37 may be reversed and the sha 'l't 32 rested thereon7 whereupon the plate will serve as a mandrel to support the shalt 'for permitting the pin to be driven into the shole in the pinion hub and shaft.

lVhen the parts are in the position just mentioned7 the shaft 92 is in line with the screw 12. rThe screw 12 is rotated by means of the handle 25 until the inner end olf the screw engages the shaft and forces it longitudinally away from the support 11 and out of the pinion.

The pinion 33 is held by the pla-te il? and the shaft is simply iorced out of the pinion. After the pinion has been removed, the plate 30 is removed trom the casing 29 by taking out the screw bolts 41, after which the rotor 31 may be removed trom the casing 29.

ln Figures 'i' and 8, l have shown another plate having in one edge a recess +14. similar to the recess 38. but smaller than the rccess 38. Adjacent to the recess 44 on one side ot the plate is a rabbet 45. .-\.t one side of the plate 43 is a small recess 46. ln the edge ot the plate 43 opposite the recess 44 is another recess 47 adapted to receive u. shaft.

lt will be understood that the plates herein mentioned are provided with recesses o` suitable size and shape for supporting the work. vWhen it is desired to remove the ball bearing device 42 trom the shaft 'l2. the plate 43 is placed in the grooves ll. as shown in Figure 2, and the shaft 32 is placed in the recesses in the plate with the hall bearing structure in 'front o1l the plain. The screw bolt 12 can then be cmpioyml Vfor forcing the sha'lit out ot the ball hearing di vice.

When it is desired to remove the heal-ilu." 4ST shown in dotted lines in Figure 1 and Figure 27 the plate 43 is inserted in the standards 123 utter the reun'ual olI the plaie 37 with the rabbet at the from. The generator or the rotor is reversed end .tor end and placed so that the bearingr 4S rests inthe rabhct 45 and the shaft rests in the recess ll. The screw 12 can then he used tor 'lori-ine the shatt- Jfrom the bearing.

The ribs help to hold. the generator in position, as illustrated especially in .Figure 4.

lt it is desired to remove the screws 49. which. extend through the casing 29 ol" the generator and hold the lield windings in place, the generator is placed transversely in the recess in the grooves 34, as illustrated by dotted lines in Figure 3. A plate 51 shown in Figures 9, 10, and 11, has spaced flanges 52 extending from one of its faces and formed with vertically spaced lingers 53. This plate is slipped into the rear plate l li) Maanen driver' 54"'for thepurpose of taking out or replacingthe screw 49.

1n? reassembling the generator, the operations performed will be readily understood.` The field windings are replaced and held in position by inserting the screws 49. rlllhe screws 49 may be tightened, iinecessary",` by placing the parts in the position shown in Figure 3, and using a wrench on the screw driver 54.

shaft, the` plate "43 is vplaced in the rear plate standards with they proper notch or recess ready to receive the bearing 48 in the rahbet The bearings are put on by hand as tar as possible. y The rotor is'placed` in. position with the bearing 48 `in the rabbet 45 oit the plate 43. The tubular` niember 57 having the closed end 58 is placed with its open end abutting against the bearing 42 andwith its opening in. register `with the shaft 32.

r1he closed end of the tubular member 57 has in its outer surface a centering recess 59.` rllhe end of the screw bolt 12 is `placed in the recess 59 andthe tubular member is i-orced rearwardly, thereby forcing the bearings onto the shaft 32. A ter the plate has been replaced the pinion. 38 vmay be forced onto the shaft 82. |1`he plate `87 is `placed in the rear plate standards ila-t sidev `forward.

The plate 43 is held with the screw bolt point 28 received in the recess 40. The rotor shaizt is placed with itsrear end against the plate 87- and in line with screw bolt The hole in the pinion 38 aligned with the front end of the shaft 82 and the screw is operated tol force the plate 48 against the pinionior forcing the latter onto the shaft 32.

1n Figures 13 to 15 inclusive, I have shown a slightly ditl'erent form of my invention adapted tor use with larger work.

ln the torni` of `invention shown in Figures 18 to 15. 1 have shown atrontsupport 80. havingthe screw bolt 82 already described, mounted therein; At the ends of `the support 80 are rearward estensione 81, having` laterally projecting portions 82. EX- tending rearwardly from the lower part of the" support 80 is a licor or bottom meis..- ber` 88.'

'llhe'` inneradjacent races oi the members 82arel provided with vertical slots 85 to receive the plates of the lrind hereinbefore described and hereinafter mentioned.

The bottom 82 is also provided with transverse groove or slot 88, the ends ot which register with the respective grooves 85.

1n the members 81 and 82 are openings 87 'and 88, as shown `in Figure 18, which are rectangular in. outline to receive bars 89. The inner holes are numbered 87, and the outer holes 88.

ing the pins selectively into the holes 92, it-

inay be `seen that the bars 89 may be locked `against movement with relation to the members 81 or 82'.

For ordinary work, the bars 89 are in serted through the openings 8'?, but where more space is necessary between the bars, they are inserted through the holes 88.

1 provide another support comprising a base 98, havingat its ends, the upright members 94 provided vwith suitable registering slots 95 on their inner adjacent surfaces. rlhe upright members 94 have lateral efrtending` parts 96.

rlhe support or base 98 has in "its bottom a slot or groove 97, the ends oi' which register with. the upright grooves 95.

in the members 94 and 96 are holes 98 and i 99 which correspond to the holes 87 and 88 pins 101 may be inserted selectively into the holes 92 for locking the bars 89 with relation to the rear support.

Pivoted to the upper part of one ot the members 94 is a locking bar 102. which has a hole 108 in its tree end adapted to project over an ear 104, which projects upwardly trom the other member 94. A pin 105 may be inserted through a suitable opening in the ear 104 ttor locking the bar 102 in its closed position.

@n the underside of the locking bar or clamping device 102 is a groove 106, the ends oi which register' with the upperends of the grooves 95, when the locking bar is in closed position. i

The device shown in Figures 13 to 15 inclusive is used in a way similar to the use of the device heretofore described. The grooves 85 may be dispensed with, it desired.

1n connection with either form of my device, plates 107 and 108 may be employed. 'lhe plates 107 and 108 may have recesses y109 and110 of suitable size to receive work.

The plates 107 and 108are preferably made olf such size that they may be superposed one upon the other in the receiving grooves with their notches adjacent to each other, so that a shaft or the like may be: Secured between the two plates.

rlihese plates are also oitl such size that their edges are received in the grooves 97, 95 and 106, and the locking bar 102 may be locked down for holding the plates with the shaft or the like clamped between them.

The base 93 may be moved farther from or closer to the support 80 to accommodate the device to the nature `of the work to be done. y

lt will be readily 'understood from the foregoing, that unless a proper tool is provided, the removal ot' the gear and bearings and the rep-lacing thereof is a clumsy operation and it the bearings are pried off or knocked oil, they are liable to be injured.

With a tool of the kind herein described, the parts may be assembled or taken apart without injury to any oi" the delicate members and in a minimum time.

The entire tool is inexpensive and simple of construction and all the parts may be packed in a small space for storage or transportation.

l claim as my invention:
